Letters Patent No. 101,836, dated April 12,1870.

IMPROVEMENT IN WHEATLDR'ILLS.

The Schedule referred to in these Letters Patent and making part0! thesame To all whom it may concern:

Be it known that I, JOSEPH DILLIEH, of Greensburg, in the county ofDecatur and State of Indiana, have invented certain new and usefulImprovements in Wheat-Drills; and I do hereby declare that the followingis a ull, clear, and exact description thereof, reference being bad tothe accompanying drawings and to the letters of reference markedthereon, which form a part of this specification, in which- Figure 1represents aside elevation of my drill.

Figure 2 is a rear view of the same.

The nature of myinvention consists in the construction of a wheat-drillwith a gutta-percha screw in the seed-box, in connection with otherdevices hereinafter described.

V A, in the annexed drawings, represents'the frame of my machine, whichis formed with the two extension bars b I), (see fig. 2.)

Toeach side of frame A is hinged a beam, 0.

(I d'represent the standards, two of which are attached to each of beamsG.

The said standards are made concave on the rear side, and each furnishedwith a shovel, s, for opening the soil. 7

To give adequate strength to the standards they are braced with rods t.

In addition to the four standards described, a fifth, ofsimilarconstruction, is secured to the bottom frame A a little inadvance of the front standards on beams E designates a driving-wheel,the axle of which is pivoted on hangers mm, the said hangers being letinto bars b b, and bolted at top to handles 1 On the same axle withwheelE is hung the bevelpinion h.

g is a vertical shaft, the upper end of which is 'pivoied in the bottomof seed-box H.

The shaft 9 is kept is posit-ion by means of a metal loop I fastened toI).

On the lower end of shaftg is hung the bevel pinion 92, which gears intowheel 74.

The top of shaft is also furnished with a bevelwheel 0, the use of whichwill be hereafter explained.

Directly above the shaft g is placed the seed-box H, the rear edge ofwhich rests on handles F, and having its ends supported by the ironstays L L.

L It designates a gntta-pcrchascrew extemlinglcngthwise of seed-box H,and pivoted in the ends of said box.

The screw is is partly sunk in a depression made in the bottom of box H,and is furnished with a hove-l whcel, 'i, which gears into wheel 0 onshaft 1.

Through the bottom of seed-box are five perforations through which thegrain is allowed to pass into a corresponding number of funnel-shapedtubes 1.

The lower ends of said tubes enter holes in beams U, and into standards(Z, and thence into the furrow.

It represents an iron rod bent at right angles at top, and passingdownward through bar '1 and slide G and then fastened to the center ofdouble lover a.

Slide G is slightly curved in shape, and its ends rest loosely in metalloops at the bottom of the hinged beams O.

To each end of lever in a metal rod, 0, is hooked, the opposite ends ofsaid rods being fastened to their respective beams 0.

It will be observed that by operating rod R, the beams G and the shovelsattached to them can be moved inward 0r outward at pleasure.

W represents a wheel hung near the front end of frame A, in order tokeep said frame on a level.

It will be seen that in order to drive the grain toward the center ofthe seed-box, the thread of the screw is reversed from the left end tothe nearest hole through which the grain is discharged.

It will also be observed that tubes I are inserted at theirjower endsinto shorter tubes which enter the perfbrat-ions in beams C, while theirupper ends are pivoted to-thc bottom of the seed-box. By thisarrangement tubes I can adapt themselves to the outward or inward motionof beam 0.

In operating my machine the driving-wheel revolves the shaft g andpinions n and c 'on said shaft, and that pinion being made 'togear intobevel-wheel j on screw k,'the seed is distributed by said screw. Havingthus described my invention,

\Vhat I claim, and desire to secure by Letters Patw cut, is

l. The gutta-percha screw 7; for distributing the seed, in the mannerset forth.

2. The combination of screw k and wheel j with shaft g, furnished withpinions n and e, the whole arranged and operated in the manner and forthe purpose substantially as specified.

3. The combination of seed-box H, furnished with screw k, wheel j, shaftg, pinions e and n, tubes I slide G, hinged beams O, and standards (Z,the whole constructed and arranged substantially as set forth.

In testimony that I claim the forgoing as my own,

' Iaifix my signature in presence of two witnesses.
